2 Claims.

This invention relates generally to dry shavers and more particularly todry shavers provided with means forming a part thereof or auxiliarythereto whereby the surface to be shaved may be illuminated.

When using shaving devices of any type it is a common experience to findthat available sources of illumination are not properly placed inrelation to the mirror and consequently it is diflicult for the shaverto observe the effects of the shaving operation. 7

A particularly aggravating situation may arise where a number of peopleare attempting to shave at the same time, as might happen in thedressing room of a railroad train, when some of the shavers arerelegated to more undesirable places.

Where the shaving device is electrically operated it may also happenthat only one electrical outlet is available and where that is used forattaching the dry shaver there is no other outlet available for a sourceof illumination.

Among the general objects of my invention therefore is the provision inassociation with a. dry shaver of illuminating means that willadequately illuminate the surface to be shaved.

Among the objects of my invention is further the provision of a lightingarrangement integral with a dry shaver.

It is also among the objects of my invention to provide illuminatingmeans energized from circuits interrelated with the power circuits ofthe motor of a dry shaver.

These objects and such other objects as will hereinafter appear or bepointed out are attained by the illustrative embodiments of my inventionshown in the drawing, in which:

Figure l is a front elevational view of a dry shaver having a lightingarrangement associated therewith;

Figure 2 is a side elevation of the device of Figure 1, portions beingbroken away; and

Figures 3 to 8 inclusive are diagrammatic views illustrative of variousilluminating arrangements adapted for association with a dry shaver.

Referring to the drawing in detail, I have shown at A in Figures 1 and 2a dry shaver of the conventional type provided with motive power meansconfined within a casing and actuating a shaving head, indicated at S,mounted in the casing. A plug P enables connection to a source ofelectric power for the purpose of energizing the motive means and alsoto supply energy to a lighting arrangement such as is indicated at L.

As appears from Figure 2 I have shown two lighting arrangements L, oneon the left side and the other on the right side of the casing of theshaver, and these arrangements L are so positioned that the lightthereof will be directed on to the surface to be shaved, and thissurface is consequently illuminated on both sides of the shaving head S.In order to make them highly effective they may be placed sufiicientlyclose to the shaving head to provide illumination of suflicientintensity, and further, if desired, a reflecting arrangement R may beprovided in back of the lighting arrangement L to distribute the lightthereof most eifectively.

While two lights L have been shown in Figure 2 it is to be understoodthat this is an arbitrary number selected by way of example for purposesof illustration, and that for certain purposes more than two lights, oragain only one light, I

may be found desirable. It is also to be understood that I do not intendto restrict myself to the exact type of shaving device shown, nor to theexact positioning of the lights L in relation thereto.

In Figures 3 to 8 inclusive I have shown a number of electrical circuitsadapted for use with an electrically operated shaving device providedwith electrically energized illuminating means.

Referring first to Figure 3 I have therein shown a motor of the magnetictype having a field magnet I0 energized intermittently by the field coill2, a rotating armature I4 and a make and break device Hi to control thefield coil circuit that is intermittently closedin synchronism with therotation of the armature H, as for example by an eccentric l8 carried byor coupled to the armature shaft. The illuminating arrangement has beenshown in the form of two neon lights 20 and 22 connected in parallel toeach other and to the motor across the line, which may be conventionalvolt house lighting circuit. Neon lights have the advantage that theyare suiliciently rugged to withstand the handling to which a dry shaveris subjected, and the conditions of its operation, and this is true bothof their mechanical as well as electrical characteristics. In the latterrespect they are better able to withstand the fluctuations in voltagedue to the action of the make and break device of a magnetic motor thanare incandescent filament bulbs intended for operation on 110 voltcircuits of sufllciently small size to be suitable for use inassociation with a dry shaver. However I do not intend to restrictmyself in connection with the circuits shown to the use of neon lightsas these are shown by way of example merely, and any suitable orpreferred type of electric light source may be used.

While I have shown a motor of the magnetic type in Figure 3, becausesuch motors are customarily employed to operate dry shavers, it willaevaoei be obvious that the circuits illustrated are equally suitablefor motors of any type.

In Figure 4 I have shown a motor similar to that of Figure 3, having afield magnet 30, a field coil 32, an armature 34, a make and break 36and means for operating the make and break 3!. A light 40 shownillustratively as of the neon type is connected across the make andbreakso that the high tension, high frequency currents resulting from thesudden opening and closing of the make and break may be utilized toenergize the light 40 and in turn the light 40 will serve to absorbthese currents and improve the action of the motor, this action beingsimilar to that of a condenser.

In Figure 5 I have again shown a magnetic motor provided with a fieldmagnet 50, energized by the field coil 52, a rotating armature 54, and amake and break 56 actuated by means 58. The lighting arrangement in thiscase is shown as consisting of a low voltage incandescent bulb S0drawing current from a coil 82 surrounding the field magnet. The coils52 and 52 constitute in effect a transformer or induction coil wherebythe periodically interrupted 110 volt current, whether alternating ordirect, serves to energize the coil 62. However during thistransformation the potential of the 110 volt house lighting circuit islowered so as to adapt it for operation of the lamp 60.

In Figure 6 is shown a motor of the magnetic type having its fieldmagnet I0 energized by a field coil 12 that has a make and break device16 in series therewith, and this make and break device is operated bythe eccentric l8 rotated in synchronism with the armature I4. Thelighting arrangement comprises a low voltage illuminating device, suchas the incandescent bulb 80, energized from a section of the coil 12 asby tapping off a lead at the point 82. This arrangement may beconsidered either as an auto-transformer construction, in which thevoltage is reduced as a result of the transformation of the potential,or it may be considered as a shunt arrangement, or as an arrangement inwhich a resistance constituted by the untapped section of the field coil72 is in series with the light 80.

In Figure 7 I have shown an arrangement bulb l4 supplied with current bytapping the field coil 12 as shown at 88. It will be observed that bythis arrangement greater eiilciency may be attained than if both lightswere in parallel on the same tap, as overloading of a section of th coilis prevented by the more uniform distribu-w tion.

In Figure 8 I have indicated at an electrical motor in series with apair of incandescent bulbs 92 and 94. This arrangement illustratesanother manner of using incandescent bulbs, of voltages other than 110,rather than using volt bulbs, which are apt to be too delicate inconstruction or excessively large for the purposes here intended. Itfurther illustrates the use of the illuminating means in series with themotor used to actuate the dry shaver, whereby a motor designed for lessthan 110 volts may be used on a 110 volt circuit.

It is to be understood that the circuits of Figures 3 to 8 inclusive maybe varied, as to the type of motor used, the number of lights, and theelectrical circuits connecting them. For example, any suitable orpreferred number of lights connected in series, parallel orseries-parallel may take the place of those shown.

While I have herein disclosed several illustrative embodiments of myinvention, it will be understood that my invention may be embodied inmany other forms, as will be obvious to those skilled in the art,without departing from the spirit thereof, and that the disclosureherein is by way of illustration merely, and is not to be interpreted ina limiting sense, and that I do not limit myself other than as calledfor by the prior art.

Having thus described my invention and illustrated its use, what I claimas new and desire to secure by Letters Patent, is:
